Goblins vs Gnomes

Goblins vs Gnomes is the first Hearthstone card expansion. It was announced during BlizzCon 2014, and will be released December 8th 2014. The expansion includes 120 new collectible cards, which can be purchased for gold or real money through a new card pack.

Expansion Information

We've organized all the facts about Goblins vs Gnomes below. If sources have not been cited, the information comes from BlizzCon 2014.

Cards

The expansion contains over120 collectible cards.

New cards will all be available in the store once the expansion launches. No waiting like in the Naxxramas adventure.

Cards are found in a new type of card pack, which is separate from the expert set. Packs contain 5 cards.

Packs cost 100 Gold, or can be purchased using the same real money pricing structure as expert packs.

All cards can be crafted and disenchanted by using Arcane Dust.

The Arena

Expert packs will no longer be rewarded from the Arena when GvG releases. The GvG packs will be the new pack reward.

All the Goblins vs Gnomes cards will be available in the card pool on release. Like before, you don't need to own them to pick them in Arena.

Spectator Mode will be available when GvG releases.

You can spectate games your friends are in, but only if they have spectating enabled.

You can invite friends to spectate your games.

You cannot see the opponent's cards if you are spectating your friend.
